The current scriptreplay utility provides a valuable tool for replaying shell scripts. However, it lacks interactive controls for playback position & speed, These could improve productivity when replaying as some recordings might have both large time-gaps that are required to be skipped while also include quick changes that require fine movement over the recording or even pausing it to read.

Additions i suggest are and key-bindings:

• Pausing and resuming playback: space to toggle.
• Adjusting playback speed: up/down (arrows), +/- 0.1x steps, hold for change of 0.1x/0.2 sec.
• Stepwise navigation: left/right (arrows), hold for change of 1 step/0.2 sec.
• Add this info and key-bindings to docs/man.
• Optional: When paused show info about current speed, position (and last step) and pause/play state.
• Optional: When step/playback speed changes show info about current speed, position (and last step) and pause/play state for 3 seconds.

I find myself often open the log file in an editor and scrolling as this is faster for some cases then replaying without the suggested change.

I don't mind contributing code toward this but i do want some feedback about the feasibility of this change as well as ways to improve the plan.
